A home is a castle, but not a castle in the 
air. A home is lumber — 2x4 studs, 1x8 
boards, 2x10 joists. Today this lumber is 
graded for specific uses. Each grade — 
No. 1, No. 2 and No. 3, for example, in 
Douglas fir and West Coast hemlock fram- 
ing lumber — is designed to meet certain 
requirements. In any well -constructed 
house there are places where No. 1 be- 
longs. But there are many places also 
where the wise builder with an eye for 
savings finds that No. 2 and No. 3 amply 
meet the need.

There are economies to be made, too, in the selection of Douglas fir and West Coast hemlock 






No. 3 Dimension: A utility grade valuable for studding 
in walls and partitions, solid bridging and filler pieces. 

No. 2 Dimension (HOOf): A stress grade used extensively 
for joists, rafters and planks. Where extra stiffness is re- 
quired it may be used in a larger size as an alternate for a 
higher grade of a smaller size. (Stiffness is determined by 
size rather than by grade.) 

No. 1 Dimension (1450ft: A stress grade of higher rating. 
For joists, rafters, plank and similar horizontal load bear- 
ing members. Mueh used in truss framing. 

Select Structural (1900f Douglas fir, 1600f West Coast 
hemlock): A high grade combining exceptional strength 
and appearance. Mostly used in engineered structures and 
for architectural effect in exposed trusses, beams, joists, 
rafters and for heavy roof sheathing where appearanee is of 

(NOTE: No. 2 Doujrlas fir and West Coast hemlock joists and rafters can be used conservatively on spans not exceed- 
ing three-fourths the maximum allowable span for No. 1 joists and rafters of the same thickness and depth.) 



Using the proper grades of lumber 
ins lower eosts — money saved. 

Douglas fir and West Coast hemlock 
dimension lumber provides absolute de- 
pendability for specified uses. With that 
dependability assured, the thrifty home- 
builder can "find" money for other pur- 
poses by selecting the proper grades. 

Because of the knots, short strips of bark, white srakfl 
pitch pockets or other characteristics which distinguish 
the grade. No. 3 is not as pretty us No. L/1*ut the 
"prettiness" of surfaces which are not exposed is of no 
importance. Of eery great important is Ou requirement 
that a hotm ht "built to last." It inusr be sound. The 
builder must know it is sound. Xo/3 Douglas fir and 
West Coast hemlock lumber, used/Where it belongs, can 
give him that assurance — at a/saving! 

For one-story walls, 2x4 studs of No. 3 Douglas fir and 
W est ('oast hemlock are widely used because of their 
stiffness, ruggedness, permanence and economy. In 
two-story Western frame construction. No. 2 studs are 
used for the ground floor and No. 3 Studfl for the uppc 
floor. In each case engineering experience has deter- 
mined that the grade will provide the required strength 
with a reliable margin of safety to spare. 

In addition to studs, sub-floors, sheathing and m< 
boards, other established uses for No. 3 Douglas fir an 
West Coast hemlock include: 

a. firestops 

b. bridging 

c. plates

"B & Better" F.G. : For covered floors or where better wear- 
ing qualities of vertical grain are not required but appearance 
is important, as in closet floors.

Knot holes may be cut out and high grade short length floor-

Comfort counts in home -building, and 
proper insulation means comfort. An inch 
of wood has insulating qualities equal to 
4 l h inches of ordinary bricks, 7 inches of 
concrete, or J2 f /2 inches of stone. That's 
why wood sheathing has been preferred 
for centuries. 

The primary requirements for roof boards and sheathing . 
are ease of working, ease of nailing, and moderate 
shrinkage. Douglas fir and West Coast hemlock boards 
are supreme in meeting these requirements. No. 3 can 
be counted on to give sound, lasting value — at a figure 
your pocketbook will like. 

For your own protection make sure that the following 
is included in your written specifications: 

"All grades shall conform to the grades as published in 
the official grading and dressing rules of the West Coast 
Bureau of Lumber Grades and Inspection." 

You know your home will be beautiful. Make sure it is 
soundly — and economically — built by using the right 
grades of lumber in the right place. 


There are economies, too, in the selection of the following types of siding: 


M Clear" v.g. Cedar, "A" v.g. Spruce and "B & Better" v.g. 
Hemlock: Highest quality wood siding, entirely vertical grain 
and practically free from all defects. The wide widths permit 
broad exposure, and the unusually thick edges produce pleas- 
ing shadow lines. 

"A" Cedar, "B" Spruce and "C" Hemlock: For high qual- 
ity construction, usable without waste. Permits mixed vertical 
and flat grain, but contains no defects that will not cover with 
paint . 

"B" Cedar: A slightly lower grade than "A" Cedar. By cut- 
ting out a few defects a paint grade for medium quality con- 
struction is obtained. 

"C" Cedar, "C" Spruce and "D" Hemlock: Is adaptable to 
use by cutting out more serious defects. An economical grade 
for medium or low cost construction.
